FIELD OF THE INVENTION

Traditionally, dramatic improvements in the treatment of cancer areassociated with identification of therapeutic agents acting throughnovel mechanisms. One mechanism that can be exploited in cancertreatment is the modulation of protein kinase activity. Signaltransduction through protein kinase activation is responsible for manyof the characteristics of tumor cells. Protein kinase signaltransduction is particularly relevant in, for example, renal cancer,gastric cancer, head and neck cancers, lung cancer, breast cancer,prostate cancer, colorectal cancers, and hepatocellular carcinoma, aswell as in the growth and proliferation of brain tumor cells.

Protein kinases can be categorized as receptor type or non-receptortype. Receptor-type tyrosine kinases are comprised of a large number oftransmembrane receptors with diverse biological activity. For a detaileddiscussion of the receptor-type tyrosine kinases, see Plowman et al.,DN&P 7(6): 334-339, 1994. Since protein kinases and their ligands playcritical roles in various cellular activities, deregulation of proteinkinase enzymatic activity can lead to altered cellular properties, suchas uncontrolled cell growth that is associated with cancer. In additionto oncological indications, altered kinase signaling is implicated innumerous other pathological diseases, including, for example,immunological disorders, cardiovascular diseases, inflammatory diseases,and degenerative diseases. Protein kinases are therefore attractivetargets for small molecule drug discovery. Particularly attractivetargets for small-molecule modulation with respect to antiangiogenic andantiproliferative activity include receptor type tyrosine kinases c-Met,KDR, c-Kit, Ax1, flt-3, and flt-4.

The kinase c-Met is the prototypic member of a subfamily ofheterodimeric receptor tyrosine kinases (RTKs), which include Met, Ron,and Sea. The endogenous ligand for c-Met is the hepatocyte growth factor(HGF), a potent inducer of angiogenesis. Binding of HGF to c-Met inducesactivation of the receptor via autophosphorylation resulting in anincrease of receptor dependent signaling, which promotes cell growth andinvasion. Anti-HGF antibodies or HGF antagonists have been shown toinhibit tumor metastasis in vivo (See Maulik et al Cytokine & GrowthFactor Reviews 2002 13, 41-59). c-Met overexpression has beendemonstrated on a wide variety of tumor types, including breast, colon,renal, lung, squamous cell myeloid leukemia, hemangiomas, melanomas,astrocytomas, and glioblastomas. Additionally, activating mutations inthe kinase domain of c-Met have been identified in hereditary andsporadic renal papilloma and squamous cell carcinoma. (See, e.g., Mauliket al., Cytokine & growth Factor reviews 2002 13, 41-59; Longati et al.,Curr Drug Targets 2001, 2, 41-55; Funakoshi et al., Clinica Chimica Acta2003 1-23).

Inhibition of epidermal growth factor (EGF), vascular endothelial growthfactor (VEGF), and ephrin signal transduction will prevent cellproliferation and angiogenesis, both of which are key cellular processesneeded for tumor growth and survival (Matter A., Drug Disc. Technol.2001 6, 1005-1024). Kinase KDR (refers to kinase insert domain receptortyrosine kinase) and flt-4 (fins-like tyrosine kinase-4) are both VEGFreceptors. EGF and VEGF receptors are desirable targets for smallmolecule inhibition. All members of the VEGF family stimulate cellularresponses by binding to tyrosine kinase receptors (the VEGFRs) on thecell surface, which causes them to dimerize and become activated throughtransphosphorylation. The VEGF receptors have an extracellular portionwith immunoglobulin-like domains, a single transmembrane spanningregion, and an intracellular portion containing a split tyrosine-kinasedomain. VEGF binds to VEGFR-1 and VEGFR-2. VEGFR-2 is known to mediatealmost all of the known cellular responses to VEGF.

Kinase c-Kit (also called stem cell factor receptor or steel factorreceptor) is a type 3 receptor tyrosine kinase (RTK) that belongs to theplatelet-derived growth factor receptor subfamily. Overexpression ofc-Kit and c-Kit ligand has been described in variety of human diseases,including human gastrointestinal stromal tumors, mastocytosis, germ celltumors, acute myeloid leukemia (AML), NK lymphoma, small-cell lungcancer, neuroblastomas, gynecological tumors, and colon carcinoma.Moreover, elevated expression of c-Kit may also relate to thedevelopment of neoplasia associated with neurofibromatosis type 1(NF-1), mesenchymal tumors GISTs, and mast cell disease, as well asother disorders associated with activated c-Kit.

Kinase Flt-3 (fms-like tyrosine kinase-3) is constitutively activatedvia mutation, either in the juxtamembrane region or in the activationloop of the kinase domain, in a large proportion of patients with AML(acute myeloid leukemia) (See Reilly, Leuk. Lymphoma, 2003, 44: 1-7).

Accordingly, small-molecule compounds that specifically inhibit,regulate, and/or modulate the signal transduction of kinases, includingc-Met, VEGFR2, KDR, c-Kit, Ax1, flt-3, and flt-4, are particularlydesirable as a means to treat or prevent disease states that areassociated with abnormal cell proliferation and angiogenesis. One suchsmall-molecule is Compound I, know also by its chemical nameN-(4-[(6,7-Dimethoxy-4-quinolinyl)oxy]phenyl)-N′-(4-fluorophenyl)-1,1-cyclopropanedicarboxamidewhich has the following chemical structure.

Compound I is disclosed and claimed in WO2005/030140, the entirecontents of which is herein incorporated by reference. WO2005/030140describes the synthesis of compound I (Table 2, Compound 12, Example 48)and discloses the therapeutic activity of this molecule to inhibit,regulate, and/or modulate the signal transduction of kinases (Assays,Table 4, entry 289). Compound I may be used as the malate salt.

Although therapeutic efficacy is the primary concern for a therapeuticagent, the pharmaceutical composition can be equally important to itsdevelopment. Generally, drug developers endeavor to discover apharmaceutical composition that possesses desirable properties, such assatisfactory water-solubility (including rate of dissolution), storagestability, hygroscopicity, and reproducibility, all of which can impactthe processability, manufacture, and/or bioavailability of the drug.Accordingly, discovery of pharmaceutical compositions that possess someor all of these desired properties is vital to drug development.

Compound I Pharmaceutical Composition

The Compound I pharmaceutical composition is a tablet comprisingCompound and excipients selected from the group consisting of a filler,a binder, a disintegrant, a glidant, and a lubricant, and optionally maybe coated or uncoated.

Compound I

In one embodiment, the pharmaceutical composition comprises Compound Ias the free base.

In another embodiment, the pharmaceutical composition comprises Compoundas a hydrate.

In another embodiment, the pharmaceutical composition comprises Compoundas a salt.

In another embodiment, the salt of Compound I is the malate salt.

In another embodiment, the malate salt is the L-malate salt of CompoundI, which has the following structure.

In a further embodiment, the malate salt is the D-malate salt. In afurther embodiment, the malate salt is the D,L-malate salt.

The malate salts of Compound I, particularly the L malate salt, have apreferred combination of pharmaceutical properties for development.Under the conditions of 25° C./60 percent relative humidity (RH) and 40°C./60 percent RH, the L-malate salt of Compound I showed no change inassay, purity, moisture, and dissolution. The DSC/TGA showed theL-malate salt of Compound I to be stable up to 185° C. No solvent losseswere observed. The uptake of water by the L-malate salt was reversiblewith a slight hysteresis. The amount of water taken up was calculated atabout 0.60 weight percent at 90 percent RH. The L-malate salt wassynthesized with good yield and purity greater than 90 percent and hadsufficient solubility for use in a pharmaceutical composition. Theamount of water associated with this salt was calculated at about 0.5weight percent by Karl Fischer analysis and correlates with TGA and GVSanalysis.

The L-malate salt of Compound I itself, and separately its crystallineand amorphous forms, exhibit beneficial properties over the free baseand the other salts of Compound I. For example, the hydrochloride saltof Compound I exhibits undesirable moisture sensitivity, changing phaseupon exposure to high humidity (75 percent RH) and high temperature (40°C.). The maleate salt had low solubility. The tartrate salt had lowcrystallinity and low solubility. The phosphate salt exhibited an 8percent weight gain due to absorption of H₂O, the highest among thesalts tested.

The water solubility of the various salts was determined using 10 mgsolids per mL water. The salts were prepared in a salt screen byreacting an acetone solution of the free base with stock tetrahydrofuran(THF) solutions of a range of acids in about a 1:1 molar ratio. Thetable below summarizes the water solubility and other data relating tothe free base and each salt.

Each of the N-1 and N-2 crystalline forms of the L-malate salt and theD-malate salt of Compound I and the crystalline form N-1 of the D,Lmalate salt of Compound I have unique characteristics that candistinguish them one from another. These characteristics can beunderstood by comparing the physical properties of the solid stateforms. For example, Table 4 lists characteristic XRPD peak positions(°2θ±0.2 °2θ) for the crystalline D,L malate salt of Compound I, FormN-1 and Forms N-1 and N-2 of the crystalline L-malate salt of CompoundI. Amorphous forms do not display reflection peaks in their XRPDpatterns.

The unique reflections between Forms N-1 and N-2 of the crystallineD-malate salt of Compound I are designated by an asterisk (*). Asdiscussed above, the D-malate salt of Compound I is an enantiomer of theL-malate salt of Compound I and thus, Form N-1 of the D-malate salt ofCompound I will have the same characteristic reflection pattern andunique peaks as those listed in Table 4 for the L-malate salt ofCompound I, Form N-1. Likewise, Form N-2 of the D-malate salt ofCompound I will have the same characteristic reflection pattern andunique peaks as those listed in Table 2 for the L-malate salt ofCompound I, Form N-2. The L- and D-malate salts of Compound I aredistinct from one another based on their absolute stereochemistry, i.e.,the L-malate salt versus the D-malate salt, respectively. Thecrystalline D,L malate salt of Compound I, Form N-1, is distinct as theD,L-malate salt.

The characteristic peaks from the solid state NMR may also serve todistinguish the crystalline and amorphous forms disclosed herein. Forexample, Table 5 lists characteristic solid state ¹³C NMR peaks for thecrystalline D,L-malate salt of Compound I, Form N-1, crystallineL-malate salt of Compound I, Forms N-1 and N-2, and the amorphous formof Compound I.

Process

In another aspect, the disclosure is directed to a process for makingpharmaceutical formulations comprising Compound I. In one embodiment,the formulation is a tablet formulation.

In another embodiment, the process comprises mixing Compound I with oneor more of the pharmaceutical excipients. The mixture is then taken upin an aqueous solution containing a binder to form a binder solution.The binder solution is granulated using a granulation technique known inthe art. For example, the granulation method may comprise wet high sheargranulation using a wet high shear granulator. The resulting wetgranules are then screened and dried using fluid bed drying or the like.The dried granules are then milled. The resulting dry milled granulesare then mixed with a glidant and a disintegrant to form anextra-granular blend. A lubricant is then blended into the extragranularblend to form the final blend. The final blend is subsequentlycompressed to form the compressed tablet, which may be film coated.

More particularly, the process comprises delumping Compound I as neededprior to mixing with the excipients. Delumping ensures that the CompoundI mixes homogeneously with the other excipients during the formulationprocess. Delumped Compound I is then mixed with microcrystallinecellulose, such as Avicel PH102, lactose (anhydrous, 60M), andcroscarmellose sodium. This mixture is then combined with EXF gradehydroxypropyl cellulose in water to form a binder solution, which isthen wet high shear granulated. The resulting wet granules are wetscreened and then fluid bed dried according to methods available to theskilled artisan. The resulting dried granules are milled and combinedwith colloidal silicon dioxide and croscarmellose sodium. Magnesiumstearate is added to the mixture. This final blend is then ready fortablet compression. The resulting uncoated core tablets are subsequentlyfilm coated. The film coating comprises Opadry Yellow, which containshypromellose, titanium dioxide, triacetin, and iron oxide yellow.

More particularly, the formulation process comprises:

-   -   a) Delumping unmilled Compound I;    -   b) Premixing the delumped Compound I with Avicel PH102, lactose        anhydrous 60M, and croscarmellose sodium to form a binder        solution;    -   c) Wet high shear granulation of the binder solution to produce        wet granules;    -   d) Wet screening of the wet granules to produce wet screened        granules;    -   e) Fluid bed drying of the wet screened granules to produce        dried granules;    -   f) Dry milling of the dried granules to produce dried milled        granules;    -   g) Blending the dried milled granules with colloidal silicon and        croscarmellose to produce an extragranular blend;    -   h) Lubricant blending of the extragranular blend and magnesium        stearate to produce a final blend;    -   i) Tablet compression of the final blend to form an uncoated        core tablet; and    -   j) Film coating of the uncoated core tablet.

General Methods of Analysis of Crystalline Forms of Compound I andCompound I, Malate Salt

Crystalline forms may be prepared by a variety of methods including, butnot limited to, crystallization or recrystallization from a suitablesolvent mixture, sublimation, growth from a melt, solid statetransformation from another phase, crystallization from a supercriticalfluid, and jet spraying. Techniques for crystallization orrecrystallization of crystalline forms of a solvent mixture include, butare not limited to, evaporation of the solvent, decreasing thetemperature of the solvent mixture, crystal seeding of a supersaturatedsolvent mixture of the compound and/or salt thereof, crystal seeding asupersaturated solvent mixture of the compound and/or a salt fromthereof, freeze drying the solvent mixture, and adding antisolvents(countersolvents) to the solvent mixture. High throughputcrystallization techniques may be employed to prepare crystalline formsincluding polymorphs.

Crystals of drugs, including polymorphs, their methods of preparation,and the characterization of drug crystals, are discussed in Solid-StateChemistry of Drugs, S. R. Byrn, R. R. Pfeiffer, and J. G. Stowell,2^(nd) Edition, SSCI, West Lafayette, Ind. (1999).

In a crystallization technique in which a solvent is employed, thesolvent is typically chosen based on one or more factors including, butnot limited to, solubility of the compound, crystallization techniqueutilized, and vapor pressure of the solvent. Combinations of solventsmay be employed. For example, the compound may be solubilized in a firstsolvent to afford a solution, followed by the addition of an antisolventto decrease the solubility of the compound in the solution andprecipitate the formation of crystals. An antisolvent is a solvent inwhich a compound has low solubility.

In one method that can be used in preparing crystals, the L-malate saltof Compound I can be suspended and/or stirred in a suitable solvent toafford a slurry, which may be heated to promote dissolution. The term“slurry,” as used herein, means a saturated solution of the compound,wherein such solution may contain an additional amount of compound toafford a heterogeneous mixture of compound and solvent at a giventemperature.

Seed crystals may be added to any crystallization mixture to promotecrystallization. Seeding may be employed to control growth of aparticular polymorph and/or to control the particle size distribution ofthe crystalline product. Accordingly, calculation of the amount of seedsneeded depends on the size of the seed available and the desired size ofan average product particle as described, for example, in ProgrammedCooling Batch Crystallizers,” J. W. Mullin and 1. Nyvlt, ChemicalEngineering Science, 1971, 26, 3690377. In general, seeds of small sizeare needed to effectively control the growth of crystals in the batch.Seeds of small size may be generated by sieving, milling, or micronizinglarge crystals, or by microcrystallizing a solution. In the milling ormicronizing of crystals, care should be taken to avoid changingcrystallinity from the desired crystalline form (i.e., changing to anamorphous or other polymorphic form).

A cooled crystallization mixture may be filtered under vacuum and theisolated solid product washed with a suitable solvent, such as, forexample, cold recrystallization solvent. After washing, the product maybe dried under a nitrogen purge to afford the desired crystalline form.The product may be analyzed by a suitable spectroscopic or analyticaltechnique including, but not limited to, differential scanningcalorimetry (DSC), x-ray powder diffraction (XRPD), andthermogravimetric analysis (TGA), to ensure that the crystalline form ofthe compound has been formed. The resulting crystalline form may beproduced in an amount greater than about 70 weight percent isolatedyield, based on the weight of the compound originally employed in thecrystallization procedure, and preferably greater than about 90 weightpercent isolated yield. Optionally, the product may be delumped bycomilling or passing through a mesh screen.
